The correct answer is option 'B': Democratic political process.

Explanation:
The development goals of different sections of society can be achieved through the democratic political process. Here's why:

1. **Inclusiveness**: The democratic political process ensures that all sections of society have a voice and representation. It allows for diverse perspectives and interests to be considered and incorporated into decision-making processes. This inclusiveness is crucial for addressing the development goals of all sections of society.

2. **Participation**: In a democratic political process, citizens have the opportunity to actively participate in shaping policies and decisions that affect them. This participation allows for the identification of specific development goals and the formulation of strategies to achieve them. It ensures that the needs and aspirations of different sections of society are taken into account.

3. **Peaceful Resolution**: The democratic political process provides a peaceful platform for addressing grievances and resolving conflicts. Through dialogue, negotiations, and the rule of law, issues can be discussed, debated, and resolved in a peaceful manner. This is in stark contrast to options like force, violent agitation, and terrorism, which often lead to further violence and destruction.

4. **Accountability and Transparency**: Democracy promotes accountability and transparency in governance. Elected representatives are accountable to the people and can be held responsible for their actions and decisions. This accountability ensures that the development goals of different sections of society are taken seriously and that progress is monitored and evaluated transparently.

5. **Policy Formulation**: The democratic political process allows for the formulation of policies and laws that address the development goals of different sections of society. Through the involvement of various stakeholders, including experts, civil society organizations, and citizens, policies can be crafted to meet the specific needs and challenges faced by different sections of society.

6. **Social Cohesion**: Democracy fosters social cohesion by promoting mutual respect, tolerance, and understanding among different sections of society. By engaging in democratic processes, individuals and communities can work together towards common goals, overcoming divisions and building a more inclusive and harmonious society.

In conclusion, the democratic political process is the most effective and desirable means to achieve development goals for different sections of society. It ensures inclusiveness, participation, peaceful resolution, accountability, transparency, policy formulation, and social cohesion. Other options like force, violent agitation, and terrorism are counterproductive and often lead to further divisions and conflicts.
